Technical Field

[0001] The utility model relates to the technical field of self-adjuster assembly, and more particularly to a return spring press-fitting device for a self-adjuster. Background Art

[0002] Self-adjuster is an important part of brake, such as Figure 1 and Figure 2 The figure shows a common brake self-adjuster, which has a main body and a rod fixed on one side of the main body. A spring needs to be mounted on the rod. In order to limit the spring on the rod, a retaining ring needs to be mounted on the rod, and then the retaining ring is limited by a gasket stuck on the outside of the rod, thereby fixing the spring between the retaining ring and the self-adjuster main body. A slot is provided on the outside of the rod to realize the clamping of the gasket on the rod.

[0003] During the production process of the self-adjuster, after the spring is put on the rod, the retaining ring needs to be pressed. During this process, the spring needs to be compressed. However, since the diameter of the spring is much larger than the diameter of the rod, during the compression process of the spring, the external force acting on the spring cannot be guaranteed to completely overlap with the axis of the spring. As a result, the middle section of the spring is very easy to deviate to one side during the compression process, which affects the performance of the spring and requires manual restoration of the shape of the spring after pressing, reducing the efficiency of the pressing operation.

Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application. In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] Example: A return spring press-fit device for a self-adjusting device, see attached Figure 3 -Attached Figure 4 , including a positioning mechanism 5, a positioning sleeve 8 and a pressing plate 9. The positioning mechanism 5 is used to position the self-adjuster body and make the rod 1 on the self-adjuster body fixed on the positioning mechanism 5 be located at the top of the self-adjuster body and in a vertical state; the positioning sleeve 8 is arranged above the positioning mechanism 5 and is sleeved outside the spring 2; the pressing plate 9 is arranged above the positioning sleeve 8 and can move up and down, and the pressing plate 9 is provided with a through hole 91 that vertically penetrates the pressing plate 9 for the rod 1 to pass through.

[0025] When in use, the self-adjuster is fixed on the positioning mechanism 5 so that the rod 1 on the self-adjuster body is located at the top of the self-adjuster body and is in a vertical state, then the spring 2 is sleeved on the outside of the rod 1, and then the positioning sleeve 8 is sleeved on the outside of the spring 2, and then the retaining ring 3 is pushed downward by the pressure of the pressing plate 9 to compress the spring 2 until the groove 11 outside the rod 1 for clamping the gasket 4 is located above the pressing plate 9, and the gasket 4 is manually clamped on the groove 11 outside the rod 1, and then the pressing plate 9 is moved upward, while the retaining ring 3 is first left outside the rod 1 due to the obstruction of the gasket 4 and the spring 2 is compressed between the retaining ring 3 and the self-adjuster body. During the process of compressing the spring 2, due to the limiting effect of the positioning sleeve 8, the spring 2 can be prevented from deviating to one side, and no subsequent manual correction is required, thereby improving the efficiency of the press-fitting.

[0026] Specifically, the positioning mechanism 5 includes two support plates 51, which are arranged along the length direction of the self-adjuster. The top of the support plate 51 is provided with a groove 511 that penetrates the support plate 51 along the arrangement direction, and the bottom of the self-adjuster cooperates with the grooves 511 on the two support plates 51.

[0027] Specifically, the positioning mechanism 5 further includes a cylinder 52 , which is provided in pairs. The two cylinders 52 are respectively located on the sides of the two support plates 51 that are away from each other, and the piston rods of the two cylinders 52 are respectively pressed against the two ends of the self-adjuster.

[0028] In this embodiment, the self-adjuster body is positioned by two support plates 51, and is fixed by two cylinders 52 which are respectively clamped at both ends of the self-adjuster body, so that the self-adjuster body is not easily displaced during the process of pressing the retaining ring 3.

[0029] Specifically, a clearance groove 81 penetrating through the side wall of the positioning sleeve 8 is provided on the side of the positioning sleeve 8 close to the operator.

[0030] Specifically, a lifting plate 82 is fixedly connected to the bottom of the positioning sleeve 8, and the lifting plate 82 can slide in the vertical direction. The setting of the lifting plate 82 can drive the positioning sleeve 8 to slide up and down, so that after the retaining ring 3 is press-fitted, the positioning sleeve 8 can slide upward to separate the positioning sleeve 8 and the spring 2, making it easy to remove the completed self-adjuster.

[0031] Specifically, a mating hole 92 is provided at the bottom of the press-fit plate 9 to match the retaining ring 3, and a magnetic ring 93 is provided at the top of the mating hole 92 to attract the retaining ring 3. The provision of the mating hole 92 facilitates the positioning of the retaining ring 3, allowing the retaining ring 3 to be more accurately press-fitted onto the rod 1. The provision of the magnetic ring 93 allows the retaining ring 3 to be adsorbed into the mating hole 92, allowing the retaining ring 3 to follow the downward movement of the press-fit plate 9 for press-fitting, eliminating the need for the operator to limit the retaining ring 3, thereby improving the convenience and safety of the operation. In order to ensure that the gasket 4 can also pass through the press-fit plate 9 smoothly, the diameter of the through hole 91 on the press-fit plate 9 is set to be larger than the diameter of the gasket 4.

[0032] Specifically, this embodiment further includes a base plate 6 and a vertical plate 7. The base plate 6 is arranged at the bottom of the two support plates 51; the vertical plate 7 is fixedly connected to the side of the base plate 6 away from the operator, and the lifting plate 82 and the pressing plate 9 slide up and down on the vertical plate 7 and are driven by a hydraulic cylinder connected to the vertical plate 7 to slide up and down.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
